I recently started using ETS again, and purchased version 5 professional. (if I'm not mistaken)
I remember going throug some procedure to move or copy the license key to the stick.
Today, I'd like to step through my old ETS 3 course (2007 - 2009).
For this it would maybe helpfull to install ETS 3 (I still have an elderly laptop with Windows XP that I also use for Simatic PLC software). So I searched and found Vassilios Lourdas post with the links to ETS 3 and ETS 4. Perfect! Thanks for that!
Now my question:
How easily can I use my Key to back and forth between ETS 3 and ETS 5?
Or would it be easier to purchase a suplementary key?
Thanks for helping out!!
